Pension Lump Sum vs Annuity Calculator
Compare a pension lump sum versus monthly annuity payments.
Find which option gives more total value over your expected lifetime using a present value analysis.
Pension lump sum vs annuity is one of the most important retirement decisions. A lump sum gives you a large one-time payment, while an annuity provides steady monthly income for life.
Annuity total value formula:
Total Annuity Value = Monthly Payment × 12 × Years of Payments
Lump sum future value with investment:
Future Value = Lump Sum × (1 + Annual Return)^Years
Key factors to compare:
| Factor | Lump Sum | Annuity |
|---|---|---|
| Control | Full control of money | No control, fixed payments |
| Risk | Investment risk is yours | Pension fund bears the risk |
| Inflation | Can invest to beat inflation | Usually fixed (no inflation adjustment) |
| Longevity | Can run out | Guaranteed for life |
| Inheritance | Remaining balance passes to heirs | Payments typically stop at death |
Break-even analysis: The “break-even point” is how many years of annuity payments it takes to equal the lump sum. If you expect to live beyond this point, the annuity may be better.
Break-even Years = Lump Sum / (Annual Annuity Payment)
Investment return assumptions:
- Conservative: 4–5% annually (bonds, CDs)
- Moderate: 6–7% annually (balanced portfolio)
- Aggressive: 8–10% annually (stocks)
Practical considerations:
- If you have other guaranteed income (Social Security, rental income), a lump sum may give you more flexibility.
- If you have no other guaranteed income, the annuity provides a safety net.
- Consider your health and family longevity when estimating how long you will receive payments.
- Some pensions offer survivor benefits (reduced payments to your spouse after your death).
Tip: Many financial advisors suggest the annuity if you expect to live 20+ years in retirement and have no other guaranteed income sources.
